Pollination Security for Fruit and Vegetable Crops in the Northeast (collaborative project with Frank Drummond, Aaron Hoshide, Sam Hanes, Alison Dibble at UMaine)


January 2012 - May 2019


Pollinator-dependent crops require a readily available source of pollinators. Although honey bees provide this service for a variety of crops, a diverse pollinator community is needed to ensure sustainability in this service. Native bee pollinators potentially contribute to this sustainability, however, knowledge about factors that affect their abundance and distributions is lacking. We are collaborating with a larger team of scientists to examine a variety of factors that potentially affect native pollinators of blueberries. Our focus is to understand relationships between native pollinators of wild blueberries and the landscape composition and arrangement around wild blueberry fields.
